Abstract

The aim of the present invention is to provide a separate-type rotary engine which significantly reduces vibrations and weight as compared to conventional cylinder-type internal combustion engines, which is simple in configuration and thus reduces manufacturing costs, which directly generates rotary force rather than through a crankshaft to increase mechanical efficiency, and in which a compressor and a force generator are separated from each other to enable the simple design of an engine suitable for a variety of uses. The engine of the present invention shown in figure 1 comprises: said compressor and force generator including housings (1, 1'), each of which has a circular inner cross-sectional surface; rotors (3, 3'), each of which has a circular or elliptical shape or a combination of a circular and elliptical shape, and rotates with one side thereof contacting the housing and the other side thereof spaced apart from the housing using the center of the circular inner space of the housing as an axis; and hinged vanes (9, 9'), each of which has one end hinged to an upper portion of each of the housings (1, 1') and the other end contacting each of outer surfaces (4, 4') of the rotating rotors (3, 3') to prevent a drop in the pressure of the compressed air and combustion gas during compression and expansion. The thus-configured compressor and the force generator are further provided with a compressed air tank (12) interposed between a one-way check valve (11) and a compressed air valve (13) to store high-pressure compressed air, wherein the open/shut operation of the compressed air valve (13) is controlled in accordance with the rotation position of the rotor (3') of the force generator, so as to store high-pressure compressed air; a fuel nozzle (15) for injecting fuel into the compressed air discharged at a high speed from the compressed air tank (12); an ignition device (16) for burning fuel in a combustion chamber (7); a gas exhaust port (18) formed at an end of an exhaust space (6-4) to discharge combustion gas to the outside of the engine; ; and an air intake port (17) formed at a front end of an air intake space (6-1) of the compressor to serve as a passage for introducing air from the outside of the compressor. The engine of the present invention is advantageous in that one combustion is performed per one rotation of each of the rotors, each of the rotors is located dead center in each of the housings rather than being eccentric, the expansion stroke of combustion gas is significantly longer to reduce vibrations and to improve engine efficiency as compared to a rotary engine (Wankel engine), and the compressor and the force generator are arranged independently from each other on a same rotary axis to enable easy changes in the sizes thereof and the simple design of an engine suitable for a variety of purposes.

Background technique

(Wankel-type rotary engine) is more simple in structure than Reciprocating engine for Wankel RC configuration, and there is every output weight and volume little, and vibration and the low plurality of advantages of noise, but be not widely used.It is because in cylinder interior, imperfect around the central axis of air cylinder sealing between triangular rotor and the cylinder of eccentric rotary around, and rotor absorbs from combustion gas between the Rotary District of power compared with short and efficiency is lower than internal-combustion engine, and durability is also low.Due to rotor eccentricity rotation, be positioned at that the Sealing on summit of triangular rotor and the wrapping angle of cylinder constantly change and cannot close contact, if Sealing weares and teares a little, its sealing effect can sharply reduce and become the reason lowering efficiency.

As having the patent rotary engine (Evan 6893) in the Hodson of British Museum Evanion Catalogue of publishing of the most ancient form with the rotary engine of Wankel RC configuration different shape.This steam engine is estimated as the patent (with reference to Fig. 4) of 1884 and comprises: cylinder; Rotor, is rotated taking the central shaft of cylinder interior as axle; Hinge joint vane, one side is articulated and connected at cylinder, and opposite side contacts at rotor outer surface, along with the rotation of rotor is carried out reciprocating rotary centered by hinged; And steam inflow device, described motor is the motor of by the power of vapor tension, rotor being given rotating force.

U. S. Patent " the combustion engine having fuel cut-off at idle speed and compressed air starting and method of operation (patent No.: 4,741,164; 1988.5.3 " be the rotary engine with the patent motor of Hodson with similar basic shape; be provided with successively: safety check; it is located between compressor module and burner module; compressor module, there is cylinder, rotor, air-chamber valve (air chamber valve) (or combustion chamber valve: firing chamber valve); Pressurized air storage tank, it has air valve, and this air valve stores residual compression air, for when the ato unit; Valve (air gate); Fuel supplying device; Firing chamber.Valve has following structure; Open by the solenoid valve being operated by rotor rotation position signal, pressurized air is supplied to firing chamber, while there is burning in firing chamber, be closed by the pressure of combustion gas.

Rotary engine (the patent No. 5 of another patent of the U.S., 247, 916), possess in addition compression eccentric wheel (compression eccentric) corresponding to compressor and power eccentric wheel (power eccentric) corresponding to power generator aspect similar to the present invention, but replace hinge joint vane 9, 9 ', different from the present invention with the aspect that powered door (power gate) forms by compression door (compression gate), described compression door (compression gate) and powered door (power gate) are to be combined in cylinder slit (slot) at rotor with a side, opposite side is state when rotation at rotor outer surface by spring contact, turnover slit inside.

The mixed cycle rotary engine (hybrid cycle rotary engine) (international application no PCT/US2007/074980) of international application also has compressor and burner module in addition, but replace hinge joint vane to utilize the rotary valve of so-called rocking bar, the rotor that described rocking bar close contact rotates in the power of the excessively other cam gear of a square tube or spring.

Summary of the invention

In background technique, replace hinge joint vane and utilize door (gate) (or rocking bar (racker)) the rotary engine (patent No. 5,247,916) and mixed cycle rotary engine (international application no PCT/US2007/074980) need push (gate) with spring etc. (or rocking bar (racker)) make it close contact at rotor outer surface, on the rotor of High Rotation Speed, need a very powerful spring in order always to contact.For this spring is set, need sizable space, this can cause the maximization of motor.

U. S. Patent 4,741,164 (1988.5.3) motor, will be sent to burner module by gate valve at the air of compressor module compression, remaining compressed-air-storing, possessing the pressurized air storage tank of air valve of turnover of specialized operations air, uses in the time of ato unit.Described structure, before opening gate valve, air in the compression of compressor module cannot be from the inner space discharge of compressor module, therefore the pressure of compressor exceeds the needed air pressure in firing chamber far away and sharply rises, and sharply becomes the reason that causes greatly the efficiency that reduces motor with this energy for rotary compression machine rotor.And in the time that compressor module has compressed air, the angle of swing of the rotor of two modules is critically adjusted into predetermined relationship becomes the compressed-air actuated state that receives with the firing chamber burned chamber valve seal of burner module.

Reciprocating transmitter uses the cam mechanism rotating along with the rotation of crankshaft in order to open air valve, U. S. Patent 4,741, and 164 (1988.5.3) open the gate valve for pressurized air being supplied to firing chamber by solenoid valve.In order with the sufficient time, pressurized air to be supplied to firing chamber, after angular sensor receives signal, to open gate valve in the shortest time, for this reason, solenoid valve should be with the fastest speed responsing signal.For example, at the motor with 5,000rpm rotation, for after angular sensor receives signal, during rotor 5 degree, open gate valve, solenoid valve should execution in 0.00017 second.For instantaneous time within the shortest time is opened gate valve, solenoid valve must be very large, now the air passageways of blocking energetically high pressure compressed for gate valve.

Rotary engine is because every output weight and volume ratio Reciprocating engine are compared very little, therefore be suitable for most aeroengine, but, still have along with highly uprising, air weakens and the characteristic of the general motor that the output of motor sharply reduces, and therefore needs further to improve in order to use in more efficient aeroengine.

Utilize the rotary engine (patent No. 5 of door (gate) (or rocking bar (racker)), 247,916) and the problem of mixed cycle rotary engine (international application no PCT/US2007/074980) can be by using hinge joint vane 9,9 ' solve.Described hinge joint vane by pressurized air and combustion gas and close contact rotor outer surface 4,4 ', therefore do not need by hinge joint vane 9,9 ' shift onto rotor outer surface 4,4 ' other devices such as spring.Just, the moment sharply declining at the pressure of pressurized air and combustion gas, be the rotor point of contact of rotor 3 of compressor between articulating point 20 and suction port 17 time and, at power generator, rotor 3 ' rotor point of contact 19 relief opening 18 and articulating point 20 ' between time, because of the pressure of pressurized air and combustion gas faint by hinge joint vane 9,9 ' shift onto rotor 3,3 ' power die down, therefore sometimes need other devices such as spring.But now, compressor does not formally enter the state before compression stroke, rotor 3 ' the lifting of power generator in hinge joint vane 9 ' be rotated and start the state of sealed combustion chamber 7, the action and the performance that therefore do not have other devices such as spring also not hinder motor.

U. S. Patent 4,741, in 164 (1988.5.3), the structure that the pressurized air of motor is sent to burner module by gate valve causes the problem of the Efficiency Decreasing of motor, this problem, can be by setting gradually safety check 11 between the compressed air outlet 10 at compressor and compressed air valve 13 and compressed air cylinder 12 solves.Thus, the air compressed at compressor is all stored at compressed air cylinder 12 by safety check 11, and by only allowing the mobile safety check of a direction to block the air that is stored at compressed air cylinder 12, make air cannot return compressor, only in the time opening compressed air valve 13, just can be supplied to firing chamber 7.The volume of compressed air hose 12 is that (this number range is for illustrational for 1 to 3 times of volume of described firing chamber, can be different according to motor), compressed air cylinder 12 is all accepted the pressurized air of compressor, its pressure also can sharply not increase, and therefore prevents that the pressure of the compression volume 6-2 of compressor from sharply rising.And, although the rotor 3 of compressor is accepted rotating force by the running shaft 5 of rotor from power generator, but, compressor is just stored at compressed air cylinder 12 by suction port 17 air amounts compression, and, power generator is not directly to accept required pressurized air from compressor, but has compressed-air actuated compressed air cylinder to accept from storage, after therefore compressor and power generator 3,3 ' do not need precision to be adjusted into predetermined angle, arranges.

U. S. Patent the 4th, 741, in 164 (1988.5.3), for pressurized air is sent to firing chamber, open gate valve (gate valve) with the solenoid valve moving by electrical signal, to block the gate valve of high pressure compressed gas in order opening fast and should to open solenoid valve, also need additional device to form to make voltage, electric current and the run signal of solenoid valve operation.If replace the gate valve being moved by solenoid valve, be suitable for the valve body that utilization is generally applicable to the cam gear of automobile Reciprocating engine, or can solve described problem points (with reference to Fig. 5 and 6) along with the movement movement of hinge joint vane 9 operates the twocouese safety check 51 opening or closing.Especially, described dual way check valve is two shapes that one way stop peturn valve is faced mutually, and the stream two ends that are connected of valve body between while there is pressure difference, ball in valve body is blocked the side's that pressure is low outlet and is formed the structure being always plugged, in order to open valve body, need utilize valve rod 52 to shift ball onto a side that pressure is high from the low side of pressure limpingly, as shown in Figure 6, when the hinge joint vane of power generator starts sealed combustion chamber by rotor, the valve rod 52 being lifted by described hinge joint vane pushes away the ball of the dual way check valve 51 that compressed air closes and forms passage so that combustion gas flowing in combustion chamber (Fig. 6-b, c), possesses the fuel injection system that comprises fuel regulator and fuel nozzle, and fuel is injected in the pressurized air of discharge at a high speed, valve rod 52 is mentioned to maximum moment, operate ignition mechanism in described firing chamber and at combustion chambers burn fuel (Fig. 6-d), in described firing chamber, the pressure of combustion gas sharply rises and during higher than the pressure of compressed air cylinder, because of its pressure difference, the ball of dual way check valve 51 is brought to completely and blocks compressed-air actuated passage, thereby can cut off pressurized air flowing in combustion chamber, and combustion gas are to compressed air cylinder adverse current (6-d, e, f), in the time of rotor, hinge joint vane is opened firing chamber, most of combustion gas are discharged into expansion space and the pressure of firing chamber during lower than the pressure of compressed air cylinder, pressurized air cuts off complete the ball of dual way check valve 51 depress pressurized air and is supplied to the firing chamber of opening (Fig. 6-a).

For rotary engine being used in to more efficient aeroengine, except arranging suction port, be further suitable for the variable compression ratio compressor (Fig. 8) of the suction port that can open or close to the setting of rotor direction at the housing of compressor.Opening completely under the state of another suction port 81 that can open or close, the rotor of compressor is revealed by another suction port through compressed air till another suction port, therefore do not compress, when rotor just starts when another suction port to compress, therefore compressed air quantity tails off and compression ratio step-down (Fig. 9-c).If block another suction port completely, (Fig. 9-a), while opening completely, (Fig. 9-c) can obtain suitable compression ratio (Fig. 9-b) according to the degree opening or closing to obtain minimum compression ratio to obtain maximum compression ratio.Moreover, in the time opening another suction port completely, until rotor does not need the power for compressing by another suction port.If utilize variable compression ratio compressor, can make the motor of performance the best under various conditions.For example, in the time that separate-type rotary engine of the present invention is used as aeroengine, open another suction port at the high low height of barometric pressure and make motor operation, and close another suction port and keep higher compressed-air actuated air pressure at the high altitude of rarefaction of air, thereby can improve the performance of motor.

Embodiment

Below, describe in detail in order to reach the operational example of the present invention of described object with reference to accompanying drawing.

As shown in Fig. 2-a, 2-b, compressor compresses by the rotation of rotor 3 and the assistance of hinge joint vane 9 air sucking from intakeport 17, is then supplied to compressed air cylinder 12 by compressed air outlet 10 and pressurized air safety check 11.One end of hinge joint vane 9 keeps airtight by compressed-air actuated pressure close contact at rotor 3, in case the compressed-air actuated pressure loss.Pressurized air cuts off the adverse current to compressor by described safety check, is stored at compressed air cylinder 12 under the state of closes compression air valve 13.

In the rotor 3 ' rotation of power generator contact shell inner surface 2 ' rotor point of contact 19 by the 20 ' time of articulating point of shell inner surface 2 ' the topmost part, blocked by the hinge joint vane of the rotor 3 of power generator ' lifting the shell inner surface being caved in and form the firing chamber 7 of sealing, meanwhile, open compressed air valve 13 by suitable device and the air of compressed air cylinder 12 flow into the firing chamber 7 of sealing fast.When pressurized air flows into, flow into firing chamber 7 (Fig. 2 c reference) from being arranged on fuel nozzle 15 burner oils of compressed air channel, mixing with pressurized air.Fuel can be by being located at the front of compressed air valve 13 or the fuel nozzle at rear 15 is supplied with, and can also flow into compressor after mixing with air compressor is outside.

After pressurized air and fuel flow into firing chamber 7, compressed air valve 13 is closed, and and then ignition mechanism 16 is moved and burnt in firing chamber.Open 9 ' time of hinge joint vane when rotor 3 ' rotation, the High Temperature High Pressure combustion gas that produce out enter expansion space 6-3 and rotor are transmitted to rotating force (with reference to Fig. 2-d) from combustor exit.High-pressure combustion gas, to hinge joint vane 9 ' apply power, makes one end close contact of described hinge joint vane at rotor outer surface, thereby keeps airtight.The rotor 3 of rotation ' shift the exhaust that remains in exhaust space 6-4 onto motor outside by relief opening 18, and rotate and compress the air in compression volume 6-2 by the rotor 3 that makes the compressor that is located at identical running shaft 5.

As diesel engine, by separate-type rotary engine when the compression ignition engine, lower the size of firing chamber and improve compression ratio in case the air of being supplied with by compressed air cylinder at compressor reach can autogenous ignition and burning be supplied to the fuel of firing chamber.Bavin oil condition, the size of firing chamber is adjusted into compression ratio to be become more than 20, still, can based on fuel Smoke prevention and the compression ratio of igniting different, the therefore large I based on fuel difference of firing chamber.Fig. 3 illustrates the example that is applied as compression ignition engine.The fuel nozzle 32 of burner oil is located at and is dwindled 31 inside, firing chamber, and fuel, according to the High Temperature High Pressure autogenous ignition that dwindles firing chamber 31, does not therefore need other ignition mechanism.

Can be suitable for dual way check valve 51 (with reference to Fig. 5,6) as a kind of form of compressed air valve 13.The air that compressor sucks from suction port by the rotation of rotor and the assistance of hinge joint vane compression, is then supplied to compressed air cylinder by compressed air outlet and pressurized air safety check.Pressurized air cuts off the adverse current to compressor by pressurized air safety check, under the state of closing dual way check valve 51, is stored at compressed air cylinder.Arrive the articulating point of the topmost part of shell inner surface at the rotor point of contact of power generator rotor before, the air pressure of compressed air cylinder is higher than the pressure of firing chamber, thereby the ball of dual way check valve 51 is blocked and led to the passage of firing chamber and cut off compressed-air actuated flowing (Fig. 6-a).

Fig. 6-b is in the time that rotor point of contact passes through the articulating point of shell inner surface the topmost part, hinge joint vane rotates based on contacting with the rotor of power generator and starts sealed combustion chamber, the ball of the dual way check valve 51 that the valve rod 52 being promoted by hinge joint vane promotes to be closed by pressurized air, and the pressurized air that forms compressed air cylinder flows to the passage of firing chamber, so that pressurized air flow into the firing chamber of sealing fast, and by the fuel nozzle that is located at air passageways, fuel is supplied to firing chamber.Described dual way check valve 51, when and the two ends of the stream that is connected of valve body between while there is pressure difference, ball in valve body is blocked the side's that pressure is low outlet, thereby there is always pent structure, should utilize valve rod 52 that ball is promoted from the high side of the low directional pressure of pressure limpingly in order to open valve body.

Valve rod 52 rise under maximum state finish to supply with to firing chamber pressurized air (Fig. 6-c), then, the ignition mechanism running in firing chamber and the (Fig. 6-d) that burns in firing chamber.Now, in firing chamber, the pressure of combustion gas sharply rises and exceeds the pressure of compressed air cylinder, and because of its pressure difference, the ball of dual way check valve 51 completely up pushes away and blocks compressed-air actuated passage, thereby cuts off combustion gas to air compression tank adverse current.During rotor rotates to 6-d from Fig. 6-c, firing chamber keeps predetermined, therefore, by suitably adjusting during this period the position that igniting occurs, makes to carry out perfect combustion under predetermined.In the time of rotor point of contact process combustor exit, the hinge joint vane that contact is rotated at rotor outer surface down rotates, and also follows hinge joint vane to move down by the spring action valve rod 52 of valve rod.Fig. 6-e, f illustrates that hinge joint vane is opened described firing chamber in the time of rotor, now combustion gas are revealed in expansion space, the pressure step-down of firing chamber simultaneously, but the pressure of firing chamber is still higher than the pressure of compressed air cylinder, therefore the ball of dual way check valve 51 is still blocked compressed air channel.Fig. 6-a illustrates that the rotor point of contact of power generator is discharged into motor outside at the combustion gas of power generator generation power by relief opening by relief opening, now, the ball depress of dual way check valve 51 is blocked the air passageways that leads to firing chamber by the air pressure of the pressure compressed air cylinder that change is large relatively, and therefore pressurized air can not leak in firing chamber.

Fig. 7 is another example of the present invention, be horizontally disposed with by dual way check valve 75, and by the sloped-end of valve rod 74 make, in the time that valve rod 74 is hinged blade and up pushes away, the ball of safety check is shifted substantially horizontal onto because of the effect of plane of inclination, and open the passage that leads to firing chamber 72 in upper body, in upper body 71, firing chamber 72 is set.Especially, as shown in Figure 7, because the pressure in the dual way check valve 75 of the plane of inclination running of valve rod 74 is subject to valve rod 75 performances of power of downward direction when the hinge joint vane of power generator is in order to form firing chamber centered by articulating point when fast rotational and the housing of power generator moment of colliding all the time, apply and the reciprocal power of rotating photo of hinge joint vane, with the effect that reduces to impact.

For rotary engine being used in to more efficient aeroengine, except arranging suction port 17, be further suitable for the variable compression ratio compressor (with reference to Fig. 8) of the suction port that can open or close to the setting of rotor direction at the housing of compressor.Another suction port 81 that can open or close if block completely, obtains maximum compression ratio (Fig. 9-a), while opening completely, obtain minimum compression ratio (Fig. 9-c), can obtain suitable compression ratio according to the degree opening or closing.Opening completely under the state of another suction port that can open or close, till when another suction port of rotor process, compressed air is revealed by another suction port, therefore can not compress, in the time of another suction port of rotor process, just start compression, therefore compressed air quantity tails off and compression ratio step-down.And, until rotor does not need the power for compressing by another suction port.If utilize variable compression ratio compressor, can make the motor of performance the best under various conditions.For example, in the time that separate-type rotary engine of the present invention is used as aeroengine, open another suction port at the high low height of barometric pressure and make motor operation, and close another suction port and keep higher compressed-air actuated air pressure at the high altitude of rarefaction of air, thereby can improve the performance of motor.

Hinge joint vane 9,9 ' stressed so as by pressurized air and combustion gas close contact rotor outer circumferential face 4,4 ', therefore do not need by hinge joint vane 9,9 ' shift onto rotor outer circumferential face 4,4 ' other devices such as spring.But, when the moment that the pressure of pressurized air and combustion gas sharply declines, in the time that the rotor point of contact of the rotor 3 of compressor is between articulating point 20 and suction port 17 and, the rotor 3 of power generator ' rotor point of contact 19 relief opening 18 and articulating point 20 ' between time, due to by hinge joint vane 9,9 ' shift onto rotor 3,3 ' power faint and can need other devices such as spring.But now, compressor does not formally enter the state of compression stroke, the rotor 9 ' lifting of power generator in hinge joint vane 9 ' be rotated and start the state of closed chamber 7, the action and the performance that therefore do not have other devices such as spring also not hinder motor.
